Resonant Fuchsine

#c866a6
Notes

Resonant Fuchsine (#C866A6) is a true magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (321°, 47%, 59%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Resonant
adjective

Latin resonāns, echoing — present-participle of resonate, sharing root with sonance. As a color modifier, resonant implies a saturated-and-deep-vibrating quality where the hue carries low-frequency visual richness. Sits at the bold-and-resonant end of the grid, parallel to sonorous and resounding in usage.

Fuchsine
noun

Synthetic-organic dye class first synthesized in 1859 by François-Emmanuel Verguin from aniline-and-tin-chloride. The dye was named after the fuchsia flower for its deep-magenta hue. Fuchsine color refers to a freshly fuchsine-dyed Lyon silk faille: a saturated, slightly cool deep magenta with the silky luster of synthetic aniline dye. Contemporary with mauveine, solferino, and the Battle of Magenta.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
